MOLD-CARRIER OF MAGHINES FOR CASTING PRINTING-BARS.

Application filed July 13, 1911.

T '0 all whom it may concern:

Be it known that l, HEINRICH DEGENER, a subject of the German Emperor,residing at Hollmannstrasse 26, Berlin, S. in the German Empire, haveinvented new and useful Improvements in the Mold-Carriers of Machinesfor Casting Printing- Bars, of which the following is a specifica tion.

In a machine for casting printing bars, the complete casting combinationconsists of (a) a horizontal row of matrices held between two jaws, theformative cavities in the face of the said row constituting the mold forthe printing edge of the printing bar; (6) a horizontally slotted moldfor the body of the printing bar, fast on or to a mold carrier; and (c)a metal pot having a pump and a delivery mouth adapted to makemetal-tight contact with one face of the mold. The mold carrier and moldare between the row of matrices and the delivery mouth of the metal pot.The other face of the mold must be presented to the row of matrices, orthe latter to the former, for the purpose of placing the said face andthe face of the row of matrices close to and opposite to each other andthe slot and row of formative cavities likewise close to and opposite toeach other. The presenting motion of the mold carrier may be circularabout a fixed center as in the well known Mergenthaler machine knowncommercially under the trade mark linotype the mold of which is carriedon a wheel; or linear as in the monoline machine; or arcual as in theForth graphot-ype machine. But there must be a further motion betweenthe mold and the row of matrices for the purpose of making their facesmake operative (2'. 6., metaltight) contact with each other. This motionhas up to the present been always only a linear one at right angles withthe said faces. Now these two faces are intended to be always parallelwith each other. If they were so, this further motion would alwayssufiice to effect the desired metal-tight contact. But accidentalfactors, such as changes in its temperature, frequently put the mold outof parallel; and when it is out of parallel, a perfect metal-tightcontact is impossible, because as the connection between the moldcarrier and the organ of the machine which supports it is a rigid one,the said mot-ion cannot be continued after Specification of LettersPatent.

one part, say one end, of the mold is in contact with the row ofmatrices.

The object of the present invention is to provide for a supplementaryfurther motion automatically effecting a perfect metaltight contactbetween the said faces. It is attained by the substitution of a looseconnection for the rigid one above mentioned, and one which is loose soas to rock either about an axis at right angles with the axis of thecarrier or in any direction about a point in that axis, so that as soonas one part of either the mold or the row of matrices, is in contactwith the other row or mold as the case may be, the other parts maycontinue to move .until all are in contact, whereby the. desired perfectmetal-tight contact is effected.

The accompanying drawing illustrates one constructional form of theinvention, the mold, mold carrier, and mold carrier support, being thoseof the Mergenthaler machine above mentioned. This form is characterizedby the carrier having a capacity for being rocked in any direction abouta point in its axis.

Figure l is a rear elevation and Fig. 2, a plan.

1 is the row of matrices; 2, 3, the two jaws; 3*, the mold wheel orcarrier; 4:, a mold; 5, the horizontal slot in it; 6, the axle fast tothe carrier 3 and turning in a bearing 7 hitherto rigidly connected by abracket to a slide 8 working in a guide 9 fast on the machine frame 10and which slide allows of the further motion above mentioned. The saidbracket is replaced by the combination of a ball 11 fast on one end of astout stem 12 having its opposite end fast to the bearing 7; a cup forthe ball 11, one half of which is formed in a block 13 fast to the slide8, the other half being formed in a second block 14 secured to the block13 in such'a way that the two halves form a proper cup for the ball 11after the manner of a cup and ball oint; and an outwardly flared hole 15between the half cup in the block 14 and the face of the latter next thebearing 7, for the stem 12 to pass through and rock in any direction asfar as the correction of the non parallelism between the mold 4 and therow 1, may require. This non-parallelism will show itself, if at all, atthe end of the above mentioned further motion. The delivery mouth of themetal pot then makes contact with the rear face of the mold, next pushesthe latter forward, thereby making the carrier and everything fast toit, rock until the faces of the mold 4 and row 1 are in the desiredmetal-tight contact with each other.

Having described my invention, I declare that what I claim and desire tosecure by Letters Patent is 1. In a typo-graphical composing machine,the combination of a mold and supporting means therefor, the saidsupporting means comprising a universal joint, so that the mold may rockabout a plurality of intersecting axes in orderto insure its' tightcontact with the other: casting devices.

2. In a typographical casting machine, the: combination of the frame,the mold carrier, and a universal joint. connection between them topermit the mold carrier to rock or tilt,

3. In a machine for casting printing bars, the combination of moldwheel; mold wheel bearing; mold for the printing bar; mold' wheel slidestem fast on the mold wheel bearing; and a loose connection between thestem and the mold wheel slide, adapted to allow the mold wheel to berocked as operative contact between it and the row i of matrices, isbeing made;

t. In a machine for casting printingbars, the combination of mold wheel;mold wheel bearing, mold for a printing bar; mold ,wheel slide; stemfast on the mold wheel bearing; and a ball and socket joint between. thesaid slide and stem,

5. In a typographical casting machine,the

combination of the mold wheel, the mold wheel slide, and a universaljoint between I the wheel and slide.

6. In a typographical machine comprising casting mechanism, thecombination of a slotted mold, and a llne of matrices to engagetherewith for al-inement, one of said elements being loosely mounted sothat it may be rocked relativeiy' to the other during the. al iningaction in a plane parallel or sub st'antially so with the face of themold. by the said engagement of. the matrix. line with a the mold.

7. In a typographicalmachinecomprising casting mechanism, thecombination of a mold carrier, a line of matrices to engage therewrthsfor alinement, the sand; carrier being mounted so that at the time of valinement it may be rocked in its own plane relatively to the matrixline by the said en-' gagement of the matrix line with the carrier. Inwitness whereof I have hereunto set my hand intlre presence of two)witnesses; v HEINRICH. DEG'ENER.
